Abstract: The mobile phone signal shielding system based on optical fiber transmission system adopts a new digital scrambling technology with higher interference efficiency and combined with the networking mode of optical fiber distribution architecture. It is different from the current digital shielding system based on indoor distribution system architecture. It does not need to build a complex antenna indoor distribution system, which reduces the construction threshold for the application of digital scrambling shielding technology.It not only improves the networking capacity of the system, but also remotely controls the end shielding nodes. On the premise of low radiation, full system, no interference with the base station and accurate perimeter control, it can also reduce the system cost and facilitate the promotion of the system.
